FRICTION-ROLLER FOR WIRE CABLES.

gPEClPICATlON forming part of Letters Patent No. 319,217, dated June 2, 1885.

Application filed October 15, 1884.

To all whom it may concern:

Be it known that I, THOMAS W. FLYNN, of Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented a new and useful Improvement in Friction-Rollers for Wire Cables, of which the following is a full, clear, and exact description.

My invention consists in an improved friction-roller for use with running wire cables where they need support, and is so constructed and arranged as to prevent rapid wear on either the cable or roller, as hereinafter de scribed and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional elevation of the roller and its supports, and Fig. 2 is a transverse section on line 00 a: of Fig. 1.

A A are stands fixed to their base or sup- 7 port and carrying the boxes B, in which the roller 0 is journaled. The boxes 13 are held in place by guides D on the stand, so that they are free to move vertically, and are pressed upward by spiral springs E beneath them. The roller 0 is preferably made of wood, so as not to wear the cable. These rollers may be (No model.)

used at mine slopes and levels, in street cable railways, and wherever a running cable is used, either to prevent sagging or at changes of level or direction. The stands are to be set according to the special location. The roller being allowed by the springs to give way to pressure and also turning freely, the wear is reduced to a minimum. The roller also allows alimited amount of side sway of the cable instead of confining it as grooved wheels do, and thus furnishes a wider wearing-surface.

The stands protect the boxes, and, if desired,
